Hi! I went on your site to find more information on how to get the Pi to create it's own network and the link to the Pi site is broken. I searched all over on how to get the Pi to create it's own network but everything I can find requires an ethernet connection. Do you have more information on how I can configure my Pi 4 to create a network I can connect to with a tablet to run VNC with no ethernet/wifi.

Excellent video as always Julian. There are two key take-aways from this and similar videos. 1. You actually use your gear in the field under field conditions. 2. Taking gear into the field, you quickly find out where the excess weight and hardware flaws are. I highly encourage everyone who is truly interested in field ops to pack everything, carry it around their yard then deploy it in the backyard without going back inside for those "other parts". While very basic, this will still show you where you're carrying too much or what you're lacking. Once you can walk to your backyard and get on the air without external support, expand it to the neighborhood ballfield...rinse and repeat. These small, simple tests will quickly show where your deficiencies are and will make for a far more effective and enjoyable deployment in the future. As for me, my next "deployment" is Winter Field Day 2020. Hope to see you on the air.

I found on Amazon a board that takes a very wide voltage input and has a fan to keep the Pi cool. It also has a switch to shut down the Pi. Not sure if it cuts power or does it normal software shut down. I think it has the pins on it to put another board on top of it. If so then you could put the board with the power supply and fan on top of the Pi and another board on top of that. This may make the Pi start to get taller, and not easy to find a case to fit it. But it will take something like 9 to about 16 volts, keep your Pi cool and give something like 4 or 5 amps of power to the Pi. I don't think you will need more power than that. But everyone has what they think is most important for their application. THANK YOU FOR THE INFORMATION YOU GIVE!

Sounds like a good one. Be careful with the fan Cooling. Fans create noise on HF. If you don't live in a terribly hot environment, passive cooling is definitely better. Anyway without seeing that bored, it's difficult for me to answer if another board can be stacked on top. I think the best bet would be sending a message to the seller Anne asking about the stacking capabilities. If designed correctly, it should be no problem.
@donaldsmith30484 жыл бұрын
@@OH8STN The best part is the buck convertor to take 10 to16 volts to 5 volts with power leftover for the Pi 4 to 5 amps at 5 volts. Not sure if it will make noise, it said low noise but that could be sound. I think there is a way to switch the fan on and off if needed. I live in south Florida. If working Pi4 the fan may be needed. Working outside with 95F weather fan may help. I will check on some things and see. Don't know if a Pi3 will need a fan. The fan has a plug to the board so can be unplugged. It does have the header pins on top of it to put another board on top of it. Just a idea if you want. It does use a plug coming out the side but it looks like you can put wires to the board and run them out the back and put power pole on it. My next 2 disability checks are spoken for but I want to get it later this year. When I get it I can tell you more about it.

Hi Julian, great video. Couple of notes: The FTDI chipset "problem" was designed into the *Windows* drivers to attempt to stem the flow of cheaper Chinese chips. Linux systems (including the RPi) don't care if the serial chip is "real" or "fake", they both work just fine. Also, if anyone is concerned about putting audio signals from the audio interface directly into the radio (can go bang), cheap 1:1 transformers (in the form of "ground loop isolators" of the sort you can get on eBay for pence) are the way forward.

I agree with you 100%!!! I am tired of the rats nest of wires we have to contend with wether it be field or ham shack centered. Once we can come up with a very clean and compact digital station it would be nice if someone could create a weather proof case sized for field use. I love the Pelican products but a case with a view would be nice no matter how remote we make the station to interface with an external device, I still like to keep an eye on stuff within the case. I have used in the past an industrial spray on silicone conformal coating that protects the board from condensation issues however the problem remains with the interface ports of the Pi. All of its connectors are the weakest link in keeping it dry and operating properly. Keep up the great work and research, looking forward to the next video! 73!

Thanks again for another excellent video. I have two Raspberry Pi's sitting in a desk drawer inches from my laptop. It is my plan and has been for some time now, to get a portable digital station up and running. I've been inspired by your portable field tests and ongoing gear development. It's my opinion that Linux is clearly the way to go for portable emergency communications. Less expensive get which is totally man packable has a clear advantage over something which can only be moved with a vehicle. Likewise, gear that has a low energy demand and can be recharged via solar makes total sense. I now have the power supply side of a field station completed so can actually operate man-portable but only with phones mode. As winter sets in here in Canada, I hope to have more time to get the Pi out of the drawer and start working on the digital side of the station. Thanks for your continued inspiration.

There is a board that goes on top of the Pi that has a fan and a built in buck converter that will take anything from around 9V - 16V in and powers the Pi. It has a plug on the side that is a pain, but there are pins inside near where the plug is that will take the power in. Things can be plunged into the top of it for more things can be added on top like the battery board. This board also has a switch to do a good power down on the Pi, also has a remote control but not sure if that is needed, just something more to keep track of. Just something that you may like to look at. This board is around $40, so it will not add a lot of coast. The fan runs all the time, not sure that is needed everywhere. I live in South Florida and it is hot in the summer some air moving on the Pi can't hurt, it doesn't use that much.

Awesome video! Thank you for blazing the trail, and thanks also to AmRRON for their work. I completely agree with the reduced cable clutter and single power requirements for field work. I see the attraction of VNC control, but I'm still leaning toward a dedicated LCD and folding keyboard, with everything tucked into a box to protect it during transportation. Wireless control is great and allows a lot of flexibility, but I don't want to power the radio station and a tablet or notebook. If not for the weight and power consumption, I'd be tempted to eliminate the Pi and use a rugged notebook for rig control and digital modes, basically a field version of the QTH shack. Like you say, I hope manufacturers start to understand field use and make more integrated radios. It honestly wouldn't take much to make a turn key solution with an integrated low power Linux computer (Pi or equivalent) that could be upgraded as new software is developed. It also strikes me that, while it's great for everyone to run scripts or otherwise configure their own systems, there is also a market for people who would like to buy a pre-configured Pi with a radio specific control cable. There is plenty of opportunity to experiment with system packaging, solar power, batteries, power regulation, antennas, etc. If nothing else, I have cellular internet and downloading a 17GB bootable Pi image would bust my monthly bandwidth limit. Similarly, Northwest Radio needs to make downloadable images that Just Work (TM) with a Pi 3B and Pi 4B. Integrated hardware isn't much help when it takes longer to configure the software than it takes to buy all the hardware modules on Amazon and configure the software for these non-proprietary bits of hardware. And yeah, the cables connecting to the DRAWS hat need to be on the same side as the Pi cables. That seemingly small detail is, almost by itself, a deal breaker. I have the single jack TRRS version of the Sabrent USB sound adapter (as opposed to the MIC and PHONE ports) which makes the homemade cable slightly more compact.

Maybe in a year when I learn more I will understand more. I have some ideas but don't know enough yet to start putting it all together. THANK YOU FOR YOUR INFORMATION!

Hi Donald. Most of the confusion about what we do and how we should do it comes from not understanding yet what our own personal goals for communications or the Raspberry Pi are. That's a mistake each and every one of us has made in the past. We need to figure out what it is we would like to do even if it's just starting with one single thing. Once you understand what that one single thing is, we can start to put together a list of tasks to help you achieve that. Some operators want to take a lightweight computer on holiday with them, to run ft8. That's the kind of thing you should consider. So they don't put one less abstract goal on the table, then you can start assigning tasks to achieve that goal. If you look at it from the big picture as this video does, it becomes too abstract and difficult to understand. Does that make sense? Does that help you at all?

I'm following with bated breath! I'm working to catch up with you as my goal is to be able to work in the field independent of mains power and provide emergency comms for myself and others in a grid-down situation. I hear your frustration with the cable mess! I have an Elecraft KX3/PX3/KXPA100 that requires a sound card for digital ops. When I assemble all those cables... urgh! There has to be a better way. I have an 817ND that I intend to experiment with. Your use of the Pi for that radio is a good one. I have a small 30w PA that can boost the output when needed. I think this might be the better path than the Elecraft, as much as I like that radio. I'm looking forward to more installments. 73 de AG7TX

even tho i am not a ham radio enthusiast or an operator, by using a raspberry pi for ham radio communication, am really blown away, its all about portability..being in the field.. and carrying expensive hardware..to communicate is a hard selling point for me, so raspberry pi comes to the rescue..Am only wondering if this complete setup can be taken to extreme by going to either Alaska, Siberia, Northern Canada or even the Sahara desert, will this setup perform the same...(of course going to these locations you might have to update the timezone and sat-com data before hand) Thankyou for the video.. stay safe..

You've inspired me. Having just acquired a Pi4 and a Ft-897 for home use. Eventually, I'll make my existing FT-857 with another Pi4 into my field ops kit. A couple of quick question though... any difficulties dealing with the heat from the PI CPU? I've noticed a big difference between the PI4 & the PI3. Is the PI3 your preferable choice?
@OH8STN4 жыл бұрын
Outstanding. You know, to be honest with you if I hadn't ft-897 I was using at home, I would use that empty battery compartment underneath for Raspberry Pi. I'm really sad they discontinue the eight nine seven. Anyway welcome to the Raspberry Pi world :-)

OH8STN well you just stunned me, I never would of thought of using the battery compartment for the Pi! That’s inspired! Although I’d think it’d mess with WIFI. Anyway, I’m making use of the low-profile CNC Aluminum passive heatsink cases available. Makes for a very secure container, yet allows access to all the pins & ports on the PI Board. I was wondering if heat is an issue with your PI’s especially with a HAT & a nearby RF Amp.

Very cool setup. You put a lot of work into this project. Have you considered multiplexing the cabling between the radio and the CPU ? Would reduce it to one cable . I imagine one could 3d print a properly spaced connector body so the breakout from the cable to device ports would be clean. Would be modular as well. Thanks for sharing !
@OH8STN4 жыл бұрын
Honestly didn't think about multiplexing. Is there a benefit for such a short cable run? For both rigs, I thought about handmaking leather case covers. Like the old binocular/equipment covers from early exploration times. It would cover and protect the rig/pi, enclose the cables, and have a satchel style from flap, to access the front panel radio controls. So I thought of hiding the cables rather than some other solution.
@survivalcomms4 жыл бұрын
@@OH8STN The benefit would be cosmetic Just having one cable and perhaps a common ground. The leather covers are cool . I made one for my 817 years ago but repurposed it. A small map case would make a great template.

Great video, I'm glad to see you mentioning AmRRON (which I am a member). I's funny you mentioned the script because I just spent two days re-imaging 8 old laptops I had laying around with Mint Linux and then running the AmRRON Setup Script on all of them, they will all be backups to my RP4, which will also have another RP4 a a backup. That's the issue with ecomms and digital modes, you better have multiple backups if we are expecting long term SHTF scenerios, have backup SD Cards for the RP, and keep the software up-to-date once a month or so. You never know what could happen and computers are fragile, once you last computer/RP is dead, no more digital modes. Power production is my big weakness currently, so on Friday or Monday (waiting to see if there will be a sale) I'm going to purchase my first PowerFilm panel, I'm looking at the R28 to begin with, I'm excited and thanks for doing all the trail blazing Julian.

Awesome comment. Yeah we're on the same page, and AmRRon has made it much more practical to stay up-to-date. Regarding the backups, and backups of backups, Its lits of work being a fanatic, but you're absolutely right. I haven't done enough with the backup systems yet. But as you mentioned running Linux Mint, I still have that old Asus laptop buy used and older videos. Perhaps I'm going to run the install scripts on that one. It's always awesome to read your comments and insight. They come with much appreciation.

Imagine a world where the manufacturers started to consult with their clients in a meaningful way. Yes they may listen to feedback, but it is very obvious that they have been holding back on technology integrations for years. It could be due to a lack of standards in the industry, but that has never held back a decision to create a proprietary feature/protocol. Perhaps they will start to hear us more as the RasPi starts to outstretch their efforts.

Another great question. The built-in audio on the Raspberry Pi is play out only. You can play out over HDMI, or the onboard headphone output. There's no microphone facilities. That's why we use an external audio codec to augment encoding and decoding.
